H EATING-DRUM FOR LAMP-STOVES.

SPECIFICATION forming part of Letters Patent N 0. 269,423, dated December 19, 1882, Application filed November 14, 1881. Renewed October 18,1882. (No model.)

To all whom of may concern:

Be it known that I, SAMUEL W. JACKSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating-Drums for Lam p- Stoves; and I do hereby declare that the following is a full,clear, and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part ot'this specificationr The object of this invention is to produce a heating-drum forlamp or oil stoves which will be more effective in heating the air in the room in which the stove is located by inducing a current of air through the drum, wherein the same is mingled with the products of combustion from the stove; and to this end it consists in a drum having the features of construction hereinafter described and claimed.

In the drawings, Figure 1 is a central verticle section of a drum embodying my invention and the upper part of an oil or lamp stove on which it is used. Fig. 2 is a horizontal section in the line 2 z of Fig. 1, looking upward. Fig. 3 is a horizontal section in the, line 00 00, Fig. 1, looking downward. Fig. 4 is a horizontal section in the line 3 y, looking downward.

A is a sheet-metal cylindric drum, somewhat larger in diameter than the stove B, to which it is to be applied. Thelower end of thedrum is open, and provided with the arms a, projectingobhquely inward and upward, and having hooks to at their upper and tree ends, which set over the stove-top, and therebysustain the drum in position for use, as indicatedin Fig. 1. By

reason of the greater diameter of the drum an annular space, b, is afforded between the drum and the stove.

C is a deflecting-plate,-preferably ofconical form, as shown, having a central opening, 0, and secured by its margin to the wall of the drum A a short distance above the top of the stove. A little above the conical deflectingflange C is located a horizontal deflecting-disk, D, arranged concentric with the drum to give the annular passage d around it, and supported by the brackets d or otherwise.

E is a horizontal deflecting-flange projecting inwardly from the wall of the drum A, and secured between the deflecting-disk D and the drum-topA,provided with anydesired number of apertures, a, distributed over its area. In

operation the heated products of combustion rise into the lower portion of the drum A, and,

following the course indicated by the arrows stove, as well as by contact with the hot products of combustion, and thereby materially increase the temperature of the combined products and air emerging through the perforated top plate, A. v

Obviously the drum may be supported in position with reference to the stove by other forms of arms than those shown at a.

I claim as my inveutionv 1. In combination with a lamp-stove, a heating-drum having at its base, when applied to the stove, a space, 11, for the admission of air, and provided with the deflectingflange C and disk D, arranged to intercept heat radiated from the flame and to give off the same to the passing current of induced air, substantially as described.

2. In combination with a lamp-stove, B, a drum, A, provided with suitable means for supportingthe same in position, and having an open space about its base for the induction of outer air, and having the flange C, against which the'admitted air impinges, the central disk D, the flange E, andthe apertured top A, arranged and operating as and for the purposes specified.

3, In combinationwith thestove B, the openbottomed drum A, larger than the stove, and provided with the inwardly-directed books 0, arranged to engage the stove-top, and thus support the drum concentric with the stove,

substantially as shown and described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

W. O. ADAMS.
